@Farhandotcom We are currently working on a Python SDK that can be run on a variety of different platforms such as Windows, Mac OSX, and Raspberry Pi. It will also be able to control a goTenna via USB. We do not have an official release date for it yet, but it is nearing final rounds of QA testing on our side, so hopefully it will be available soon!
